6 cars are going to be at a premium now because of the two scrapped sets and the one that was broken by the split point incident in Portlaoise. Waterford is also being stuck with 3 car sets so it's not like Sligo is special - except if you count refusing Mark 3s...
Maybe it's time for Sligo County Council to tell its TDs - after the current PSO period is up we can live without Sligo airport's commercial services with its constrained runway, its ecologically sensitive to an extension hinterland and its horrific website on a direct understanding that the PSO money saved by not renewing can go towards rail line speed/passing loop upgrades to reduce journey time and thus the likelihood of starving to death between leaving home and Connolly.
Edit: apparently
extending SXL will cost EUR10m
